Specification forming apart of Letters Patent No.` M680., dated October 5, 1858:.

To @ZZ whom, it may concer/L Be it known that I, WILLIAM C. HUTCHIN- SON, of St. Joseph, in the county of Buchanan and State of Missouri, have inventedand made certain new and usef'ul Improvements in Machines for Breaking Hemp; and I dohereby declare that the following is a full, clear, and exact description of the same, reference heilig had to the accompanying drawings,,making a part of this specication, in which- Figure l is a perspective View of the maa sliding scalloped edge double-j aw hatchel 7 or beaters.

In Fig. I is a frame-like work, colnposed of suitable longitudinal and cross base rails, a a a a, and central rails I) b, top rails, c c, uprights d e d e d e, central rails f g, top cross-rail, h, and foot-board fi.

At J J is afeeding-table or hemp-platform, with obliquely-set side boards, k k.

At L is a small cylinder of suitable weight and size, provided with journal ends working in bearings m. This cylinder Iterm a press ure-feed cylinder,7 and it rests nearly in close contact with the feeding-table, and its journal ends,working in the slots of the bearing m, admit of the cylinder rising upwardly in the feeding of the machine, to accommodate itself to the quantity of feed taken in under it. In front of this cylinder is a square-edge iron bar, n n a, and contiguous to this bar is a large cylinder or drum, 0 o o, inserted in the surface, and around the circumference of which are teeth or breakers, arranged in series of rows at suitable distances, each row of teeth varying in positionrelative to each other, and

so as to appear like series of spirals around the circumference. These teeth or breakers have slightlyangular or double-sloping edges formedwith oval or rounded or beveled edges on one of the surfaces, as shown in Fig. 3, face beneath the feeding-board` J `J J. To these4 stirrups is attaclieda thinslat or strip of wood or metal, q q, witlrits edge rounded and seal# loped or ridged,asat rr. This I term the pendent swingle, or vibrating sword or beater.

At s s-s s are two correspondingly-shaped strips or slats,` with scalloped or ridged edges tt. Thesestrips are arrangedV two or more inches apart, one above the other, and relatively` arranged so *that the edge of the swingle-q r q r may` strike betweenthe jaws of the rIhese strips are attached by strips s s s s. their ends to sliding block au, provided with guide-pins working in sliding places or ways v o, Figs. l and 2. These strips I term the reciprocating or sliding doublejaw sword or hatchels.

At 'w w are connection reciprocating rods, one end of which is connected by a hinge or joint to the sliding blocks u u, and the other end attached in a similar manner to a rocking beam or arm, x x x as, arranged between the uprights d e d e, the said arms a; w being attached to one common axle; er ai?.

To the end of the cylinder o o o is a wheel or disk, y y y, (or an equivalent crank-arm,) to which is attached a reciprocating connection-rod, z z, the other end of said rod being attached to the rocking beam or arm x fr.

To the end of the machine, in a suitable position, are small rollers e202 c3 c, supported in bracket-s or bearings a2 a2 b2, and attached to the central rail of the framing. Across the middle of the machine is another roller, d2 d2, and around the rollers c2 cl d2 d'z is adjusted a short endless apron, e2 c2 e2 et.

Atf2 is another or afourth roller, arranged across the framing f f, and passing around the rollers c .c3 and fZ is a longer endless revolving carrier g2g g2 g2.

At h2 7L h2 is a driving-wheel, by which power is applied and motion comlnunicated to the machine through the smaller wheel i2, and thelarger pulley J 2, around both of which passes a crossed band or cord, k2 k2 7a2 k2, Fig. 2.

At L2 L2 L2, Fig. 2, is a main or principal sloping cap or top, with sides L3 L3 L3, and at mm2 is a secondary or smaller detachable cap, with sides m3 and a sloping call frontm2 mt. These caps or sloping tops are designed to confine and prevent the flying of the dust and particles of trash.

At n2 n2 is a hinged iiap or front, with buttons n3 to conne it in place when desired.

At the lines and. dots 0Z o2 o2 o2 o2 is represented a hinged or falling side flap, to admit ofaccess to the inside of the machine'.

The operation of my machine is as follows, viz: The hemp-stalks are placed upon the feedingtable J J J, and the roller L L receives the stalks beneath its circumference. The stalks pass under and are mashed, and then pass over the edge of the iron bar n n n, and comein contact with the beveled face ofthe teeth or breakers of the cylinder o o o, when the stalks are carried downwardly between the bar n a n and cylinder o, and are caught between the jaws rt i' t of the pendent swingle and sliding hatchel s s s s, and by the action of these ridged or scalloped edges of the swingle and hatchel the -lint and tow are completely separated from the woody` o r coarser portions of the stalk; and as the hemp reaches the carrier g2 g2 g2 it is carried forward between the surfaces oi the carrier and short endless apron e2 e2 e2, and debeing tied up, thus affording a superior iiber with much less tow and Waste than has heretofore been afforded by machinery.

Mymaohine can be built of various sizes,and operated by hand, horse, or any'other suitable motive power, and at a more expeditious and much cheaper rate than is generally the case in preparing hemp. If desired, the endless revolving carrier gz g2 g2 g2 may be extended out in length several feet beyond the end of the machine, so as to admit of carrying or bearing off at a convenient distance the woody and useless portions of the hemp and deposit them in aheap, to be burned or otherwise disposed of.V

Having given the nature, construction, and operation of my improvements in hempbrakes, what I -claim as new, and desire to have secured by Letters Patent of the United States, is-

1. Thetooth herein described and illustrated in the drawings(` as constructed, to be used in the drums of cylinder hemp-brakes, as herein set forth.

2. The combination and arrangement of the pendent scalloped-edge swingle P P P q q r i' with the sliding or reciprocating doublejaw hatchel s s s s t t, arranged and operated substantially in the manner-as herein set forth and described.
